The most fun part of this game is being able to play the missions on 2 player mode. The controls are easy to grasp and once you've played once or two missions, you'll get the hang of it and the rest of the game will be a breeze. However there are not that many things you can unlock if you finish the game once or twice. There are archives and files that you can get but if you are already a fan of the Resident Evil series, you will know all that information anyway. At least Resident Evil 4 had unlockable weapons and sidequests etc. There really isnt much of a replay value to this game despite being such fun.
The other let down is that they completely bypass Resident Evil 2 so if you are hoping to catch Leon Kennedy in this game, dont bother. He doesnt appear at all. The game covers Res Evil Zero, Res Evil 1 & 2, and thats it.
